This 2012 documentary tells the remarkable story of Rafael Schächter, a brilliant, young, passionate Czech choral conductor who was sent to the concentration camp of Theresienstadt (Terezín) in 1941. Under the most brutal of circumstances, and determined to sustain dignity, humanity, and hope within his fellow prisoners, he recruited 150 prisoners and taught them Verdi's Requiem by rote in a dank cellar using a smuggled score, after grueling days of forced labor. They performed on 16 occasions for fellow prisoners, with the last, most infamous performance on June 23, 1944, in front of high-ranking SS officers from Berlin and the International Red Cross to support the charade that the prisoners were well treated and flourishing.
